“Never take activated charcoal. It’ll strip the nutrients right out of you.”

I see some version of this all the time on social media. As usual, the nuance behind it isn’t included and it gets stated as a blanket rule instead.

I’m not saying the people claiming this are completely making it up or crazy. There’s truth to it. But there’s important nuance here that gets left out while another trending binder gets promoted instead.

The issue with this is that it prevents people from using versatile and effective tools for situations where they need them most. And it’s not just charcoal, there are other similar binders getting painted in a negative light unnecessarily.

One of the biggest issues with this conversation is the nuance around timing, digestion and where nutrients are in your body. Nutrients aren’t stored in your gut. They aren’t floating around in there waiting to get grabbed at any given moment. A binder can only bind what it physically touches, dissolved, in the gut, at the moment it’s passing through.

So the question was never “does charcoal bind nutrients.” The question is what’s sitting in your gut when you take it.

I covered the basics of binders in the post below: what they are, the ones I’ve used most, why they matter, etc.

This post will go deeper into the part almost nobody covers: how these things actually differ, why charge matters as much as timing and how to match a binder to what you’re actually trying to remove.

The real problem with binder advice online is that “binder” gets treated as one category when these are completely different tools working through completely different mechanisms.

The Nutrient Fear With Binders

Let’s start with the mechanism, because once you understand how binders actually work, the blanket warning on binders like charcoal falls apart.

Activated charcoal is one that gets a lot of hate online. It’s important to understand that it’s not absorbed. It goes in your mouth, moves through your digestive tract and comes out in your stool. It never enters your bloodstream. It never reaches your liver, your bones, your tissues or anywhere else you’re storing nutrients.

That’s true for nearly every binder people use. Bentonite clay, zeolite, Enterosgel, cholestyramine, chitosan, diatomaceous earth and standard pectin all work the same way. They stay in the gut and leave in your stool.

Two worth separating out. Chlorella is as much a food as a binder, so some of what’s in it does get digested and absorbed. And modified citrus pectin is deliberately processed to be absorbable, which makes it the one commonly used binder that can genuinely work beyond the gut. I’ll come back to that one.

Charcoal is like a lint roller moving through a tube. Things stick to its surface as it goes past. It only works on direct contact, and only on substances dissolved in the fluid around it. Your gut lining absorbs things that are dissolved and small enough to pass through it, and charcoal is a solid particle that stays solid the whole way down. The particles are too big to cross the gut lining.

So people end up with this picture in their head where charcoal circulates through your body, hunting down your nutrient stores and dragging them out. That’s not what happens.

What it can do is bind whatever is in your gut at the same time it is. Which is exactly why timing is important.

About half the people on the planet are walking around with a bacterium in their gut that can cause ulcers, gastritis and even cancer.

Most of them have no idea.

H. pylori (Helicobacter pylori) infects roughly 4.4 billion people worldwide. It’s classified as a Group 1 carcinogen (the highest cancer risk category there is), the same one that holds tobacco and asbestos. It’s associated with around 75 to 90% of duodenal ulcers and up to 80% of gastric ulcers.

It spreads primarily from person to person. Contaminated food and water are other routes, especially in countries with poor sanitation. Most people pick it up in childhood, and without treatment (because many don’t know they have it), it can quietly persist for decades or even a lifetime.

When it does get caught, most people are handed a round of antibiotics and told that’s the end of it. Sometimes that works. Often it doesn’t. And even when it does, H. pylori or other overgrowths often come right back.

Because H. pylori is rarely the whole story. It shows up in an environment that let it take hold and it leaves damage that ripples far beyond the stomach. If you only try to kill the bacteria itself and ignore everything around it, you’re setting yourself up for the exact cycle I see people stuck in constantly.

This post will break down all of it. What H. pylori is, how to know if you have it, what it’s actually doing to your body, how to confirm it and the specific things I focused on to clear it in myself and in the many people I’ve worked with who had it.

How Do You Know If You Have It?

Honestly, symptoms alone won’t always tell you.

As common as it is, many of the people who carry it never develop obvious, consistent symptoms. So the fact that it’s everywhere, yet only a fraction of carriers ever feel it clearly, makes it genuinely hard to know whether you have it just by how you feel.

The only way to know for sure is testing, which I’ll cover in detail later. That said, when H. pylori does cause symptoms, these are some of the most common:

• Dull or burning ache in the upper stomach

• Bloating and feeling excessively full early in a meal

• Frequent burping

• Nausea, sometimes with a loss of appetite

• Heartburn or reflux type symptoms

• Unexplained fatigue

• Bad breath that doesn’t resolve with normal oral hygiene

• Dark, tarry, or bloody stools, or blood in vomit

• Unintended weight loss

If several of these sound familiar, it doesn’t confirm anything on its own. But it’s a signal worth investigating rather than ignoring.

Important note: detecting H. pylori isn't always the same thing as having an active infection. Low levels can exist without causing disease, and if your stomach acid, immune defenses and overall digestive health are functioning well, it’s often kept in check. The bigger concern is when those defenses become compromised, allowing it to overgrow, or when testing confirms an established infection with enough activity to drive inflammation, tissue damage and the downstream effects covered throughout this post.

Why It’s So Good at Surviving

Before getting into the damage it causes, it helps to understand why H. pylori is so stubborn in the first place. This bacteria is built to survive in a place almost nothing else can.

It survives in the acidic environment of the stomach because it produces an enzyme called urease. Urease generates ammonia, which neutralizes stomach acid in the immediate area around the bacteria. In simple terms, it makes its own little antacid cloud so the acid that’s supposed to kill it can’t.

It also has a high mutation rate and adapts genetically, which lets it survive long term. On top of that, it’s known to be antibiotic resistant, especially to clarithromycin, metronidazole and levofloxacin.

That resistance is a big reason it’s so hard to get rid of with the standard approach.

Then there are its virulence factors. These are essentially the tools it carries to help it survive and do damage. Strains can produce factors like CagA, VacA, DupA, OipA and GGT that manipulate immune responses, promote inflammation, deplete antioxidants, increase oxidative stress and damage stomach tissue.

These virulence factors are common across many H. pylori strains, but they vary by strain and region.

When I was dealing with digestive issues, some of the worst symptom flare ups had nothing to do with what I ate, supplements I was taking or anything like that.

The rough patches always seemed to line up with something I couldn’t quite figure out.

This was a variable almost everyone underestimates and handles poorly, including a lot of practitioners. It doesn’t show up on a stool test. It’s hard to put a number on. So it gets overlooked and people keep cycling through new supplements and protocols that never touch it.

That variable is stress.

I’m not talking about the throwaway advice you’re given when your doctor tells you you have IBS. “Just manage your stress better” is one of the most useless things that many gastroenterologists say to people whose bodies are falling apart. It’s vague, it’s dismissive and it usually comes with zero real instruction or context.

For years, I didn’t really get it either. I had no idea why a stressful period alone could physically wreck my gut. Once I understood the actual mechanisms, it changed how I approached things.

Stress affects every single person to varying degrees whether they feel it or not. And it’s relevant whether you’re actively dealing with issues or not.

So, I wanted to go deeper into this. Talking about the different types of stress, why it matters so much for your gut specifically, how the gut and stress feed each other in a loop and the exact things I’ve found that actually move the needle. Not “just reduce stress,” real mechanisms and things you can start doing today to improve this.

What Stress Actually Is

Stress is your body’s response to a demand or a threat. Something shows up that requires adaptation and your physiology shifts to meet it.

The problem isn’t that this system exists. The system is brilliant and necessary. The problem is that the world has changed drastically in the last few decades and our bodies are adapted to an environment that no longer exists. Today, your body is exposed to stressors almost constantly and that response never fully switches off unless you’re deliberate about it.

There are a few different types worth separating out.

• Mental and emotional stress: worry, conflict, uncertainty, deadlines, financial pressure, social tension, rumination, the constant feeling of being behind.

• Physical and physiological stress: poor sleep, illness, infection, injury, overtraining, chronic pain, blood sugar instability, dehydration, nutrient deficiencies, inflammation, metabolic dysfunction and anything else that puts a physical demand on the body.

• Environmental stress: toxins, light environment, air pollution, loud noise, non-native electromagnetic fields (nnEMF), things acting on your body whether you consciously feel “stressed” or not.

Your body doesn’t separate stressors into neat categories before responding. A work deadline, a terrible night of sleep or a gut infection are very different experiences, but each adds to the cumulative load on the body’s regulatory systems. They can drive many of the same pathways involved in stress adaptation, including the nervous system, hormones, inflammation, energy production or recovery.

The details differ, but the body often ends up paying a similar physiological cost.

That’s something most people miss. You can be doing “stress management” in your head while your body is drowning in physical and environmental stress you never considered.

The Broad Buckets of Stress

There’s an important distinction here. Not all stress is created equal and lumping it all into one bucket labeled “bad” and something that should be avoided is where most people go wrong.

Some stress is inevitable. Some is even good for you.

Your body often adapts to challenges by getting stronger. A hard workout is a stressor. Lifting something heavy, a cold plunge, a fast, a genuinely difficult problem you have to solve. When the dose is appropriate and recovery is sufficient, your body adapts and becomes more resilient.

This is called hormesis. A manageable dose of stress, followed by recovery, triggers adaptive responses that can make the system more resilient over time.

You are never going to fully escape stress and you wouldn’t want to. A life with zero demand on it is a life of decline. Challenge is part of being healthy.

Then there’s the other kind. Unnecessary, avoidable and constant.

Doomscrolling at midnight. Watching the “news” cycle hammers you with the worst things happening on the entire planet, packaged to be as emotionally charged as possible. Arguing with strangers online. Algorithms engineered to keep you irritated because outrage keeps you engaging.

None of this is making you more resilient. There’s no adaptation on the other side. It’s just chronic, low grade activation with no real payoff.

The goal is not to eliminate all stress. The goal is to manage the inevitable stress well and ruthlessly cut the unnecessary stress that’s consistently draining you.

Few people do both consistently and effectively. That’s the opportunity.

Why This Matters for Your Health

To understand why stress can affect your gut, you need to understand one of the major control systems in your body: the autonomic nervous system.

The autonomic nervous system has two main branches. The sympathetic branch is associated with the “fight-or-flight” response. The parasympathetic branch is associated with “rest-and-digest” activities such as digestion.

These systems constantly adjust their activity based on what your body needs. When a threat or challenge appears, sympathetic activity tends to increase. When you’re safe and recovering, parasympathetic activity tends to become more dominant.

Since digestion is a parasympathetic dominant function, it runs best when your body believes it’s safe. Stomach acid secretion, enzyme release, bile flow, the muscular contractions that move food through you, and the migrating motor complex (cleaning wave that sweeps the small intestine between meals) are all influenced by autonomic nervous system activity. When your body shifts into a stress state, many of these processes can be disrupted.

Your body has no interest in digesting lunch if it thinks it’s facing a serious threat. It shifts resources away from long-term maintenance and toward immediate survival. That’s adaptive for an afternoon. It’s a disaster when it’s your default setting for months or years.

On top of this sits the HPA axis. Your brain perceives stress, signals down to the adrenal glands, you produce cortisol and a cascade of related signaling molecules. Acutely, useful. Chronically activated, this can contribute to increased intestinal permeability, disrupted immune function, changes in the microbiome and a wide range of other issues.

Now let’s get specific, because this runs in both directions.

This is part 1 of a 2-part post on IBD.

I have gotten a ton of DMs, emails and comments about IBD the last couple months so this is going to be thorough.

IBD is one of the most complex and also mishandled conditions in gut health. And in order to understand what will actually help you get relief, you need to understand how the system works and what issues are commonly involved.

That's what this post covers. How the key systems work, what commonly goes wrong and how it all ties into IBD. This is the foundation.

In part 2, I’ll walk through two real client cases. Both had ulcerative colitis. Both ended up in the ER shortly before we started working together. Both reached remission within 6 months.

I’ll break down exactly what their testing showed, how the issues we cover here were showing up in their situations and the full protocol we used to address them.

IBD Is Not IBS

This is one of the most important distinctions and it’s one that gets messed up constantly.

IBS (irritable bowel syndrome) is a label for a set of symptoms. It's uncomfortable and disruptive, but it doesn't cause structural damage to your intestines. There is no test you can run to detect or confirm you have IBS.

IBD (inflammatory bowel disease) is entirely different. It involves chronic, active inflammation that physically destroys intestinal tissue. It breaks down the mucosal lining, creates ulcers, causes bleeding and over time can cause irreversible damage to the colon and other parts of the GI tract.

The two main types are ulcerative colitis (UC) and Crohn’s disease. UC affects the colon and rectum, specifically the innermost lining (the mucosa). Crohn’s can affect any part of the GI tract from mouth to anus and penetrates deeper into the intestinal wall.

Uncontrolled IBD has real consequences.

It significantly increases the risk of colorectal cancer. One meta analysis found a cumulative risk in UC patients of about 1.6% at 10 years, 8.3% at 20 years, and 18.4% at 30 years after diagnosis. People with IBD have roughly 1.8x the colorectal cancer risk of the general population.

It can lead to other autoimmune conditions, appendicitis and systemic complications throughout the body.

For many people, it eventually leads to surgery. About 25-35% of IBD patients will require surgical management during their lifetime (I would argue this is largely because it’s mishandled in about 90% of cases). For ulcerative colitis specifically, total colectomy (removal of the entire colon) rates are over 44%. That means living with a colostomy bag permanently for many of them.

This is why getting the approach right matters so much.

A Growing Problem

IBD is not rare and it’s not slowing down.

An estimated 2.4 to 3.1 million Americans currently have IBD. That’s nearly 1 in 100 people. The United States has one of the highest prevalence rates in the world, at roughly 721 cases per 100,000 people.

And the numbers keep climbing.

The increase in cases over the past two decades can’t be explained by genetics alone. Something environmental is driving this. Diet, antibiotic overuse, toxin exposure, stress, circadian disruption. The modern environment is creating conditions for this disease to develop at a concerning rate.

Misdiagnosis Is Rampant

I’ve connected with many people who had IBD but were told it was IBS, GERD or other digestive issues for years before being properly diagnosed. They were given antispasmodics, told to manage stress, maybe prescribed a PPI and sent home while their colon was being actively destroyed.

I’ve also worked with people who were incorrectly told they had IBD but never had the testing that can actually confirm it. They were put on immunosuppressants based on symptoms and basic blood work alone.

You cannot diagnose IBD from a stool test, blood work or symptoms. The gold standard for diagnosis is colonoscopy with tissue biopsy.

Stool markers like calprotectin can suggest inflammation and imaging can help. But a definitive IBD diagnosis requires actually visualizing the tissue and confirming it.

Both misdiagnosis scenarios are dangerous. Undiagnosed IBD causes progressive damage. Inappropriately diagnosed IBD means people on powerful immune-suppressing drugs they don’t need.

This Is Personal

I had my entire life turned upside down by this disease.

I’ve worked with many clients with IBD who had the same happen. Some had already been through surgery because the medical system failed them.

That’s why I’m passionate about this. I know what it feels like to be told there’s nothing you can do except take medication and hope for the best. And I know from personal experience and from helping many others that there’s a much bigger story than what most people are being told.

How IBD Is Being Mishandled

IBD is a complicated, multifactorial condition. But it’s treated like a simple one.

Put the person on medication. Try to keep symptoms suppressed. That’s it. That’s all most medical professionals will do.

There are several reasons for this and they go deeper than most people realize.

There are massive financial incentives driving how IBD is treated. When I looked up the top recommended IBD specialist near me in the Open Payments Database, that doctor received nearly half a million dollars from pharmaceutical companies in a single year. $278,000 in speaking fees alone as a paid spokesperson for major biologic manufacturers (Eli Lilly, Janssen, Takeda, AbbVie, Pfizer).

A functional/integrative GI in the same market? $2,500 total.

Beyond direct pharma payments, there’s the buy-and-bill model. For infused biologics like Entyvio, doctors purchase the drug at wholesale and bill insurance at a markup. The spread per patient can be $13,000-17,000+ per year on biologics versus $0 from prescribing a first-line drug like mesalamine that you pick up at a pharmacy.

Insurance step therapy (trying cheaper treatments first) is supposed to happen. It rarely does.

Doctors document cases as “moderate-to-severe” from day one, use language that meets insurance criteria for biologics and cite “early aggressive therapy” guidelines that were heavily influenced by pharma-funded research.

But the financial incentives are only part of it. Doctors are also constrained by time (10-15 minute visits can’t investigate root causes), legal liability (deviating from guidelines creates risk), training bias and guideline influence (pharma funds the studies that become the guidelines).

When I was dealing with IBD, I asked multiple doctors about things like low fiber diets, herbal supplements, the importance of circadian rhythms and intestinal permeability. Most basically said I was crazy and that none of this was “supported”. All of them continuously pointed me back to pharmaceutical drugs.

Several gastroenterologist told me diet doesn’t really have that big of a role in managing IBD. That tells you everything you need to know about whether that person can help you.

I did a full deep dive on the these issues which you can access below.

Your microbiome is one of the most important factors in your digestive health. And it’s not just digestive health. Immune function, mental health, hormonal balance, skin, energy, metabolism and much more.

Your microbiome houses trillions of bacteria, fungi, viruses and other microbes. This ecosystem does way more than just help you digest food.

It produces short-chain fatty acids that fuel the cells lining your intestine. It synthesizes vitamins your body can’t make on its own. It trains your immune system to distinguish between a harmless food components and an actual pathogen. It produces and is involved in regulating neurotransmitters like serotonin. Roughly 70-80% of your immune cells live in and around your gut and the microbiome is constantly communicating with it.

When the microbiome is balanced and diverse, it helps these systems run smoothly. When it’s disrupted, things unravel both in and outside of the gut.

This is why so many chronic health issues that seem unrelated to digestion (brain fog, skin conditions, hormonal dysfunction, autoimmune flares, chronic fatigue) are often tied into gut health in one way or another.

Most people don’t understand this. And because they don’t, they spend years chasing individual symptoms without ever addressing what’s quietly driving them.

A massive amount of research over the past two decades has focused on the microbiome for exactly this reason. We know it matters. We know disrupting it has consequences. We know that restoring it can resolve or help resolve conditions that nothing else touched.

But here’s what a study published earlier this year made very clear: we are still in the early chapters of fully understanding the gut microbiome.

There are likely many important players involved here that we still know almost nothing about.

60% of Your Gut Has Never Been Studied

For most of the history of microbiology, the only way to study bacteria was to grow them in a lab. You take a sample, put it in a petri dish, give it fuel it needs to survive, control the temperature and wait.

Whatever grows, you can study deeper. Whatever doesn’t, you can’t (at least not to the same extent).

The problem is that over 60% of the bacteria living in your gut have never been successfully grown in a lab. The majority of gut bacteria are obligate anaerobes, meaning they can’t grow or reproduce when they’re exposed to conditions outside the gut.

Many of these microbes require extremely specific conditions to survive: precise pH, the right temperature, cross-feeding and relationships with other bacteria that we can't replicate in a lab.

That means for decades, the only gut bacteria we could study in any depth were the ones we could grow in a dish. The majority of the microbiome was essentially unkown to us.

Think about that for a second. We’ve built an entire field of probiotic supplements, microbiome testing and gut health protocols around the 40% of bacteria we can legitimately study. The other 60% has largely been a black box.

This started to change with testing methods like metagenomics. Instead of trying to grow bacteria, you extract the DNA from a stool sample and sequence it.

Every organism in there, living or dead, culturable or not, leaves a genetic fingerprint. Metagenomics reads those fingerprints.

A quick note here because I get a ton of questions about this: metagenomics and qPCR (which is the technology behind the GI-MAP and the preferred method in many cases) are different tools for different jobs.

qPCR is considered by many to be the gold standard for quantifying known microbes. It's precise, it's validated and it gives you specific numbers on specific microbes. That level of detail matters because not all microbes are the same.

With pathogens, they don't all respond to the same treatments. Some require more aggressive approaches, others don't. And the same is true on the beneficial side. There are commensal bacteria we've isolated, studied and understand well enough to know exactly what supports or depletes them.

qPCR can tell you how much of each one you have, which is why it can be so useful for building targeted protocols, especially in complex cases or when you need to go after a specific pathogen. These are the microbes we've formally identified, cultured and characterized over decades of research. We know their behavior and what moves the needle on them (generally speaking).

But qPCR can only measure what you already know to look for. You have to design a primer for each target, which means if a microbe hasn't been formally characterized yet, it won't show up.

Metagenomics is a discovery tool. It captures everything in the sample, including organisms nobody has formally identified yet. It’s how you find things you didn’t know to look for.

Both are valuable.

What metagenomics has shown us is a completely different picture of what's living in the gut. Researchers used this to catalog the hidden microbes and found over 3,000 species that had never been seen before.

Over 3,000 species that have been living inside human guts this entire time, and we had no idea they were there.

Many people trying to resolve digestive issues are doing everything right on paper.

The supplements make sense. The diet is clean. The protocol was built off real testing. You saw some improvement early on, maybe even felt hopeful for the first time in a while.

Then you hit a wall.

Nothing you add moves the needle. Nothing you subtract fixes it. You’re following the plan and your gut just won’t cooperate.

I’ve seen this situation more times than I can count. And in a huge percentage of these cases, the missing piece isn’t another supplement or a tweak to the diet. It’s the nervous system.

Your autonomic nervous system is the part of your nervous system that runs everything you don’t consciously control. Digestion is one of those things. It directs stomach acid, enzyme release, bile flow and the muscle contractions that move food through you. When that direction gets disrupted, the consequences stack fast.

Most people in the gut healing world are focused almost entirely on inputs. Supplements, dosing, specific foods. All of that matters. But inputs only work if the body is in a state where it can respond to them. Pour the best protocol in the world into a nervous system stuck in the wrong state and it will under-deliver every time.

This post walks through how this works mechanically, how to tell if your nervous system is the bottleneck, and what to actually do about it.

Your Gut Doesn’t Run Itself

This is a basic fact that rarely gets stated clearly enough.

Your gut doesn’t operate in isolation. It’s constantly being influenced by your autonomic nervous system, which regulates how digestion is coordinated from moment to moment.

Your gut also has its own built-in network called the enteric nervous system. This system can run many digestive processes on its own, but it still takes cues from the autonomic nervous system to adjust based on what your body is dealing with. Think of the enteric nervous system as the operator on the ground and the autonomic nervous system as the dispatcher telling it what the rest of the body needs.

Within the autonomic system, there are two branches that matter here. The sympathetic branch handles fight-or-flight, stress response and anything that prioritizes immediate survival. The parasympathetic branch handles rest, digestion, repair and long-term maintenance.

These two branches are in a constant tug-of-war. Whichever one is winning dictates how well your gut can actually do its job.

When parasympathetic activity is dominant, digestion is supported:

• Stomach acid production is normal

• Bile is released when needed

• Pancreatic enzymes are secreted more effectively

• Motility is coordinated

• Blood flow to the gut improves

• The gut lining turns over efficiently

• Immune activity is balanced

When sympathetic activity dominates, digestion gets deprioritized. Blood flow shifts away from the gut. Motility and secretions become less coordinated. Enzyme and bile output drop. Barrier function and immune signaling become more reactive and less regulated.

Here’s the problem. Most people in the modern environment spend a disproportionate amount of time in a sympathetic-leaning state. Poor sleep, chronic stress, constant stimulation, blood sugar instability, overtraining, unresolved trauma. All of it can push the system in the same direction.

When that becomes the baseline, the signals your gut depends on don’t show up consistently. You can take all the right supplements and eat all the right foods, but if the machinery isn’t getting the signal to run, none of it performs the way it should.

Over time, the downstream effects compound. And this is where most stuck cases actually live.

Fibermaxxing has been trending.

If you’ve spent any time on health social media recently, you’ve probably seen it. Dieticians posting reels telling you to eat 60 grams of fiber a day. Gurus telling you to stack psyllium husk, inulin powder, and chia seeds if you want to heal your gut. Bold claims about colorectal cancer risk if you don’t hit a specific number.

Most of it is either misleading, incomplete, or flat-out wrong for a significant portion of the people watching.

Here’s the reality with social media. It’s optimized for virality. Not truth. Not nuance. Not what’s actually going to help the specific person watching. The algorithm rewards polarizing, simple, bold claims. “Eat 60 grams of fiber a day or you’ll get colorectal cancer” gets shared. “It depends on your specific gut situation and there’s a lot of nuance here” does not.

So that’s what gets distributed. A lot of social media is blind leading blind.

Fiber is genuinely one of the most important topics in gut health. The mechanisms behind its benefits are real and well-documented. And there are equally real, well-documented reasons why for a substantial portion of people today, following the trending advice will make their situation significantly worse.

Both things are true at the same time. But you’ll almost never see both discussed together.

That’s what this post is going to do.

What Are Prebiotics & Where Does Fiber Fit?

Before getting into fiber specifically, it helps to understand the broader category it belongs to.

Prebiotics are compounds that serve as food for bacteria and other microbes in your gut. They’re not absorbed in the small intestine. They reach the colon largely intact, where the microbes that live there ferment them and produce compounds that have a major influence on your gut and overall health.

The key word is selectively. Not all compounds that reach the colon and feed bacteria are equal. Different microbes require different types, and what one species thrives on may not do much for another.

Dietary fiber is the most well-known and well-studied category of prebiotics. But it is not the only one. Resistant starches, while technically a starch rather than a fiber, behave similarly in the gut and contribute to the same downstream processes. Polyphenols, the plant compounds found in berries, olive oil, coffee, and dark chocolate, also reach the colon largely intact and selectively feed and modulate beneficial bacteria in meaningful ways.

Each of these deserves its own deep dive. But fiber is where most of the trending advice is concentrated, it’s where most of the misinformation lives, and it’s what this post is focused on.

Anna is a 34-year-old I connected with recently. She works in marketing, is sharp, a high-performer, the kind of person you can just tell is intelligent and successful within the first few minutes of conversation.

Or she used to be.

For the past two years she’d been leaving work meetings with no memory of what was discussed. She’d read the same email three times and still not comprehend it. Some days the brain fog was so bad she wondered if something was seriously wrong with her neurologically.

She’d also get bad bloating after certain meals. Had unpredictable urgency from time to time. Hadn’t felt truly comfortable in her body in a while.

Her gastroenterologist told her the digestive issues were IBS. Her GP suggested she might be dealing with too much stress and recommended therapy.

The idea that these might be connected was never discussed.

That’s the thing about the gut-brain connection. The symptoms look different enough that nobody connects the dots. But when you understand what’s actually happening biologically, the separation stops making sense.

The gut and brain are in constant communication. What happens in the gut influences neurochemistry, drives inflammation, and shapes how you think and feel on a daily basis.

And one of the most important factors in that equation is the gut lining. It’s what stands between the contents of your gut and your bloodstream. When it’s intact, it acts as a selective barrier. When it breaks down, that separation disappears, and things that were never supposed to get through do.

The gut stops being a contained system and starts driving problems throughout the body. Including, in many cases, the brain.

What Leaky Gut Actually Means

Leaky gut is the name for intestinal hyperpermeability. An increase in permeability of the gut lining that allows things to pass through that shouldn’t.

The gut lining is a single layer of epithelial cells connected by tight junction proteins that control what gets through. Under normal conditions, nutrients pass through the cells themselves. The tight junctions prevent everything else, bacterial fragments, undigested food particles, toxins, from slipping through the gaps between cells.

When those tight junctions are disrupted, that protection fails.

This is not fringe science, despite what you may have heard from conventional medicine. The mechanisms are documented in hundreds of peer-reviewed studies at this point.

The key protein is zonulin, a signaling molecule that was discovered by Dr. Alessio Fasano in a paper from 2000 (PMID: 10801176). It directly regulates tight junction permeability.

When zonulin levels rise, it triggers a chain reaction that physically pulls tight junction proteins apart, opening the spaces between cells. Short-term, this is actually believed to be a defense mechanism. It lets the immune system sample gut contents and detect potential threats quickly.

The problem is chronic exposure to modern triggers keeps zonulin high. The junctions stay open. And a short-term defense mechanism becomes a chronic liability.

What Gets Through

When the gut lining is compromised, several things enter the bloodstream that have no business being there.

Bacterial toxins are the most significant. Lipopolysaccharides (LPS), which are fragments from the outer membrane of certain bacteria, are one of the worst inflammatory triggers known. Other bacterial components like peptidoglycans and flagellin also cross a leaky gut.

Ozempic is everywhere right now. You can’t open a news app or a social media feed or a conversation without it coming up. I’ve even seen it on multiple billboards recently.

But most of the conversations and information are incomplete and misleading. Which isn’t surprising, given that most of it comes from people selling it.

The general public understanding is that it helps you lose weight. And it can. But there’s a much more important conversation happening underneath that one, especially if you’re someone who wants to actually improve their metabolic health rather than just manage the symptoms that come with issues in this area.

The question nobody seems to be asking: why did the natural systems fail in the first place?

Because here’s something most people don’t know. The hormone Ozempic mimics is made in your gut It’s called GLP-1. And more research is showing that the state of your microbiome determines, to a significant degree, how much of it your body produces.

In this post I’m going to break down what GLP-1 actually is, how your gut bacteria impact its production, what happens when the microbiome breaks down, and what I would actually do if I were dealing with weight, metabolic dysfunction, or insulin sensitivity issues right now.

This isn’t a post about whether semaglutide (Ozempic) is good or bad. This is about understanding the bigger picture, especially when it comes to going after the root of the problems that lead most people to use or consider it (or other drugs/peptides like it).

What GLP-1 Actually Is

GLP-1 stands for glucagon-like peptide-1. It is a hormone produced by specialized cells in the lining of your small intestine and colon called L-cells.

It does several important things:

• Signals to your brain that you’re full, reducing appetite

• Triggers insulin release from the pancreas in response to rising blood sugar

• Suppresses glucagon, the hormone that tells your liver to release stored glucose into the bloodstream

• Slows gastric emptying, blunting post-meal blood sugar spikes

• Has protective effects on pancreatic beta cells, the cells responsible for producing insulin

This sits at the intersection of appetite regulation, blood sugar control, and metabolic function.

Ozempic is a synthetic molecule designed to mimic GLP-1. It binds to the same receptors and delivers similar downstream signals, but with a much longer half-life than the hormone your gut produces naturally. Your body produces GLP-1 in pulses that last minutes. Semaglutide hangs around for about a week.

That longer timeframe is why it works so well for appetite control and blood sugar regulation.

But it still leaves the core question unanswered: why aren’t your body’s natural systems doing this job properly?

The Gut Bacteria Connection

This is where it gets interesting.

The L-cells that produce GLP-1 are embedded in your gut lining and in constant communication with the bacteria living there. Those bacteria produce compounds called metabolites that directly stimulate the L-cells to secrete GLP-1.

The most well-established example is short-chain fatty acids. When gut bacteria ferment dietary fiber, they produce compounds like butyrate, propionate, and acetate. These bind to receptors on your L-cells and trigger GLP-1 release. Less fiber means less fermentation, less fermentation means less short-chain fatty acids, less short-chain fatty acids means less GLP-1.

But there is a more specific connection that most people haven’t heard about.

A study in Nature Microbiology (PMID: 39805952) called out a particular type of gut bacteria called Bacteroides vulgatus as a key driver of GLP-1 secretion.

B. vulgatus produces a compound called pantothenate (vitamin B5). Pantothenate stimulates the intestinal L-cells to secrete GLP-1. That GLP-1 signal then triggers a secondary hormone in the liver called FGF21, which travels to the hypothalamus, the part of your brain that regulates hunger and sugar cravings.

The full cascade:

• B. vulgatus produces pantothenate

• Pantothenate stimulates intestinal L-cells

• L-cells secrete GLP-1

• GLP-1 triggers FGF21 production in the liver

• FGF21 acts on the hypothalamus to reduce sugar cravings

• Blood sugar regulation improves

In the mouse experiments, depleting B. vulgatus broke this entire chain. Sugar cravings went up. Blood sugar regulation worsened. GLP-1 output dropped.

When researchers restored B. vulgatus metabolites in the depleted mice, GLP-1 came back up, FGF21 rose, and sugar preference reversed.

Most people dealing with hormonal issues are focused entirely on their hormones.

That makes intuitive sense. Estrogen is off, so fix estrogen. Testosterone is low, so raise testosterone. Thyroid is slow, so medicate the thyroid.

The problem is that for a lot of people, the hormones aren’t actually the origin of the problem. They’re responding to something else. And that something else is often the gut.

This isn’t fringe thinking. The mechanisms connecting gut function to hormone metabolism are well-documented. But they rarely come up in a standard doctor appointments. So people spend years managing hormonal symptoms without ever addressing what’s actually driving the issues.

Here’s what’s often involved but being overlooked.

How the Gut Regulates Hormones

Your gut influences hormones through several pathways. These aren’t vague, indirect connections, they’re specific biological mechanisms that are important to understand if you’re dealing with hormonal disruptions.

The Estrobolome

A subset of gut bacteria produce an enzyme called beta-glucuronidase. This enzyme deconjugates estrogen in the gut, meaning it reverses the process the liver used to package estrogen for removal.

Here’s the sequence: estrogen is metabolized in the liver, bound to a carrier molecule, excreted into bile and released into the intestine to be eliminated through stool. That’s the intended path.

But if beta-glucuronidase is high, the estrogen gets unpackaged before it can leave the body, reabsorbed into circulation and added back to your total estrogen load.

This is called the estrobolome. The collection of gut bacteria that directly regulate circulating estrogen levels through this mechanism.

When microbiome diversity drops or dysbiosis develops, beta-glucuronidase activity can increase significantly. Estrogen clearance slows, recirculation rises and the result can look like estrogen dominance even if estrogen production is completely normal.

In women, that may involve:

• Severe PMS

• Heavy or irregular cycles

• Breast tenderness

• Fibroids

• Worsening endometriosis

• Mid-cycle migraines

• Fluid retention

In men, it can involve:

• Low testosterone symptoms despite normal total T

• Elevated estradiol

• Increased visceral fat

• Gynecomastia

• Low libido

• Mood instability

• Difficulty building or maintaining lean mass

This is documented in human studies on estrogen metabolism and microbiome composition. It is not theoretical.

Most people with chronic gut issues never think about their liver or bile.

They focus on things like probiotics, fiber or elimination diets. But underneath a lot of the symptoms people dealing with, the liver and bile system are quietly driving the problem.

Bloating after fatty meals, light-colored or greasy stools, nausea, right-side discomfort, brain fog, hormone imbalances, skin issues that don’t resolve no matter what you cut out of your diet.

These are common signs of issues with these systems. They’re often downstream effects of a liver that’s under intense stress, disrupted bile production or bile flow issues.

Why This Gets Overlooked

Bile isn’t just a digestive fluid. It’s a transport system. Your liver produces it continuously, your gallbladder concentrates and releases it, and when it flows properly, it does several things simultaneously:

• Breaks down dietary fats

• Kills harmful microbes

• Carries toxins and hormones out of the body

• Keeps the gut environment balanced, healthy & resilient

When that system is disrupted, the effects ripple outward. Fat-soluble nutrients don’t absorb properly. Toxins that should be leaving recirculate. Microbial overgrowths get a foothold in environments where bile would normally keep them in check. Hormones that should leave the body stick around.

The frustrating part is that conventional testing rarely catches this until it’s severe. Liver enzymes can look normal while bile flow is compromised. The gallbladder can be functioning but bile quality can be low. These aren’t issues that always show up clearly on standard blood panels.

There are targeted supplements that can make a significant difference when bile flow and liver function are part of the picture. But they aren’t all relevant or effective in every situation. This is why getting clarity matters before guessing at solutions.

Two things apply here as with any supplement approach:

First, foundations: Things like diet, sleep, stress, movement, and hydration play a huge role in how well any supplement can work. Chronic dehydration alone can thicken bile and disrupt flow. These aren’t optional.

Second, context: What’s driving the problem determines what’s useful. Someone dealing with disrupted bile flow from poor diet and sedentary habits needs a different approach than someone recovering from antibiotic-related liver stress or managing genetic methylation issues. The supplements below are useful tools, but the best results come from understanding your specific situation first.

Here are the 10 that have the strongest evidence, clearest mechanisms and that I’ve had the most success with when it comes to supporting liver function and bile flow.

At my worst, I couldn’t touch butter. No milk, no cheese, not even ghee. Any of it sent me into a spiral: bloating, cramping, rashes, alternating constipation and diarrhea.

I cut it all out and told myself I was just lactose intolerant. That was completely wrong.

I now consume what most people would consider an egregious amount of dairy. Daily. Zero symptoms.

And the reason I got there had almost nothing to do with the explanations you see on social media.

If you’ve been told to just avoid dairy forever, tried raw milk and still reacted, or eliminated it years ago and never looked back, then this post is going to challenge some assumptions.

There are five common factors that I have seen causing people to react to dairy. That’s what we’re covering today.

The Reductionist Argument That Won’t Die

Everyone on health social media has the answer to dairy intolerance: it’s pasteurization. Just switch to raw milk and you’ll be fine.

I tried that. Still reacted.

And I’m not alone. I’ve worked with plenty of people who made the switch to raw dairy and still reacted just as badly as they did before. Bloating, cramping, skin issues, the whole thing. Meanwhile I’ve also worked with people who switched to raw and felt significantly better almost immediately.

Both cases exist. Which tells you something important: if switching to raw fixed everyone, we’d have a clean answer. We don’t.

The people insisting pasteurization is the only variable are making the same mistake that gets made constantly in the health space. They found something that worked for them, got results and concluded it must apply to everyone else.

It’s understandable. But it’s wrong. And it’s doing a disservice to the people who tried raw milk, still reacted and now believe they’re just stuck. They addressed the thing everyone told them to address. It didn’t work. So they gave up.

Dairy intolerance is not a one-variable problem. There are several factors I’ve seen drive the majority of dairy reactions in the people I’ve worked with.

These are not just theories. These are things I’ve observed firsthand working with people who couldn’t tolerate any dairy whatsoever, who once we actually addressed these variables, were eating it again without any issues.

Small intestinal bacterial overgrowth (SIBO) is one of the most misunderstood and poorly treated conditions in digestive health.

It’s also a common factor behind the bloating, gas, irregular bowel movements, poor digestion and other symptoms that millions of people deal with daily.

The conventional approach is straightforward: test positive, take antibiotics, hope it works. Maybe follow a low-FODMAP diet.

Some people get lucky. But for many, it doesn’t work. And even when it does, it’s often temporary.

Estimates put relapse rates around 25% within 3 months of antibiotic treatment. By 9 months, that number climbs as high as 66%.

From my experience, those estimates are conservative. I’ve worked with countless clients who treated SIBO with antibiotics and ended up reaching out to me because it either didn’t work or came right back.

To be clear, I’m not saying antibiotics can never work. They can be effective when used properly as part of a larger strategy. But that almost never happens. Antibiotics alone, without addressing what allowed the overgrowth in the first place, is a recipe for recurrence.

SIBO is not a root cause. It’s a downstream consequence of other dysfunctions that allow it. Until those are identified and addressed, you’re playing whack-a-mole.

You knock it out for a bit. Then it resurfaces.

I’ve helped dozens of people fully clear SIBO. Not by overloading the system with antimicrobials, but by understanding what allowed the overgrowth to develop and systematically addressing those factors. And by strategically targeting the overgrowth itself using tools that are often more effective with far fewer side effects.

This post breaks down everything: the mechanisms, the common root causes, the testing, effective treatments and the nuances that most practitioners miss entirely.

The Impacts of SIBO

Your small intestine is designed to have relatively low bacterial counts compared to your large intestine. The large intestine houses trillions of microbes (your microbiome). The small intestine should have far fewer.

When bacteria overpopulate the small intestine, they ferment carbohydrates before you can absorb them. This produces gases (hydrogen, methane or hydrogen sulfide) that cause the classic symptoms: bloating, gas, irregular bowel movements, fatigue, brain fog and more.

But SIBO doesn’t just cause discomfort. It can drive serious downstream issues:

Nutrient malabsorption: Bacteria compete for nutrients and damage the surface of the small intestine where nutrients are absorbed. Deficiencies in B12, iron, fat-soluble vitamins (A, D, E, K) and others are common in people with SIBO.

Leaky gut: The overgrowth triggers inflammation that damages tight junctions, increasing intestinal permeability. This allows bacterial toxins, undigested food particles and other compounds into circulation.

Systemic inflammation: Lipopolysaccharides (LPS) from gram-negative bacteria can cross into the bloodstream, triggering immune responses that affect the entire body.

Hormonal disruption: Gut inflammation affects the gut-liver axis, disrupting hormone metabolism and clearance. Excessive beta-glucuronidase (produced by gut bacteria) can lead to estrogens and toxins recirculating.

Brain fog and mood issues: Gut inflammation directly impacts neurotransmitter production and signaling. Serotonin, dopamine and GABA are all commonly affected.

Autoimmunity: Several studies show links between SIBO and conditions like Hashimoto’s, rheumatoid arthritis and other autoimmune diseases through molecular mimicry, chronic immune activation and intestinal permeability.

This is why “just kill the bacteria” rarely works long-term. The root contributors and downstream effects are often systemic.

Small Intestine vs. Large Intestine

One nuance that most people miss: SIBO is often used interchangeably with overgrowths in general. This is not accurate. SIBO specifically refers to overgrowth in the small intestine. But the small and large intestines are fundamentally different environments with different functions.

Small intestine: Primary site of nutrient absorption. Should have relatively low bacterial counts. Receives bile, pancreatic enzymes and stomach acid to continue digestion. Movement through here should be relatively quick.

Large intestine: Primary site of fermentation and water absorption. Houses your microbiome. Fermentation of fiber here leads to production of short-chain fatty acids.

The distinction matters because:

• Testing differs: Breath tests measure gases produced in the small intestine. Stool tests primarily reflect large intestine composition. They’re measuring different things and using different methods to measure them.

• Treatment differs: The types of microbes found in the small intestine can differ from those in the large intestine. The antimicrobials that work best depend on what’s actually overgrown, not just the location.

• Root causes overlap: Many factors that allow SIBO also cause large intestine dysbiosis. Both are often seen simultaneously.

• Bacteria can migrate: If the ileocecal valve (the door between small and large intestine) is dysfunctional, bacteria from the colon can migrate upstream. You can clear SIBO, but if the valve is compromised, recolonization can happen quickly.

When I work with clients, I’m thinking about both intestines. Clearing the small intestine while ignoring large intestine dysbiosis is a recipe for it coming back.

The Three Types of SIBO (Not Two)

Not all SIBO is the same. The type of gas produced determines symptoms and influences treatment.

Hydrogen-dominant SIBO

Bacteria produce hydrogen gas from fermenting carbohydrates. This typically causes:

• Diarrhea or loose stools

• Bloating and gas

• Urgent bowel movements

• Faster transit time

Hydrogen-dominant SIBO often clears more quickly (generally speaking) because it involves bacteria that are generally speaking more responsive to standard antimicrobial treatments. In contrast, methane-dominant overgrowth involves archaea and commonly involves slowed gut motility, making it more resistant and slower to resolve.

Methane-dominant SIBO (also called IMO: Intestinal Methanogen Overgrowth)

Archaea (specifically Methanobrevibacter smithii) consume hydrogen and produce methane. Methane slows gut motility by as much as 60%. This causes:

• Constipation

• Hard, dry stools

• Severe bloating

• Slower movement through the gut

Methane-dominant cases are typically harder to treat because of this. The archaea are more resilient than bacteria and form stubborn biofilms. And the slower gut motility creates an environment where these unwanted microbes thrive.

Hydrogen sulfide SIBO

Sulfate-reducing bacteria produce hydrogen sulfide gas. This is the newest recognized form and harder to test for since many SIBO breath tests do not include it. Symptoms commonly include:

• Diarrhea (often severe)

• Rotten egg smell to gas

• Fatigue

• Brain fog

• Sensitivity to high-sulfur foods

Hydrogen sulfide SIBO requires different antimicrobial strategies and often involves addressing heavy metal toxicity (sulfur pathways are involved in metal detoxification).

These distinctions matter. A generic SIBO protocol that doesn’t account for the type of overgrowth commonly fails. Different antimicrobials are effective against different types of overgrowth, and using the wrong ones often leads to poor results.This is the case with any type of overgrowth. The specific types, levels and factors involved vary.

Why SIBO Develops

This is where most protocols fail. They focus on killing bacteria without asking why bacteria overgrew in the first place.

In my experience, SIBO rarely has a single cause. It’s usually a combination of factors that create the perfect environment for overgrowth in the small intestine. Here are the most common I see.

Low Stomach Acid (Hypochlorhydria)

Stomach acid is your first line of defense against bacteria entering the small intestine. At a normal pH (1.5-3.5), it sterilizes food and kills most unwanted microbes before they reach the small intestine.

When stomach acid is low, bacteria survive and colonize downstream.

This is why long-term PPI use is so strongly linked to SIBO. You’re removing a barrier that prevents bacterial migration.

What causes low stomach acid:

• Chronic stress (suppresses acid production)

• H. pylori infection (this can directly impact stomach acid levels)

• PPI and antacid use

• Aging

• Zinc and B vitamin deficiencies

• Hypothyroidism (strong impact on motility)

Signs of low stomach acid:

• Bloating immediately after meals

• Feeling full quickly

• Reflux (counterintuitive but often involves low acid, not high)

• Undigested food in stool

• Nutrient deficiencies despite good diet

An at-home baking soda test is a simple starting point. Mixing 1/4 tsp baking soda in 4 oz water, drinking on empty stomach and timing how long until you burp. Under 3 minutes suggests adequate acid. Over 5 minutes suggests low acid.

This page explains this in more detail.

Upgrade to Paid

“Everything looks normal.”

The most common thing people with chronic gut issues hear. And the reason most of them stay sick.

Your gut is wrecked. You know it. Your doctor’s tests just can’t see it.

A client I worked with recently had been to multiple doctors over two years. Same script every time: constant bloating, unpredictable diarrhea, pain after most meals. They’d nod, order limited blood work, call back with the same conclusion. Everything looked fine.

Meanwhile, she couldn’t eat dinner with friends without planning her escape route to the bathroom. She’d lost 15 pounds because half the foods she used to eat now destroyed her.

Her gut wasn’t normal. The testing just wasn’t looking in the right places. And once you understand why, you’ll stop blaming yourself for not getting better.

The Testing Gap

Standard gut testing is like trying to complete a puzzle with 25% of the pieces. You’re not going to see the picture.

When doctors run tests for gut issues, they’re usually doing limited blood work. Complete blood count, basic metabolic panel, sometimes TSH if you’re lucky.

These panels can’t detect dysbiosis, SIBO, intestinal permeability, bile acid malabsorption, enzyme deficiencies, histamine issues or any of the other drivers of common digestive issues.

When we ran comprehensive testing on this client, we found bacterial overgrowths, extremely low beneficial bacteria, a disrupted gut lining, liver stress and an immune system in overdrive. Multiple specific, measurable, treatable issues.

All invisible to the tests her doctors ran.

Why Proper Testing Doesn’t Happen

In my experience, most doctors genuinely want to help. But the system makes investigating these deeper issues nearly impossible.

It isn’t built to find what’s wrong with you. It’s built to process you quickly and bill insurance.

Time Constraints

Doctors are limited to 10-15 minutes per patient. They’re paid per visit, not per hour, so they need high volume to meet revenue targets. Many are given productivity quotas based on Relative Value Units that reward more visits, not better outcomes. A study in 2016 showed that doctors spent 27% of their time with patients and 49% on administrative work. Add in a massive shortage of doctors, and short visits become the only option.

Insurance

Many functional tests aren’t covered by insurance or require extensive documentation to justify. Most doctors don’t have the time or incentive to fight for approval, especially when the results won’t change what they can do within conventional care anyway.

Liability

Some doctors avoid comprehensive stool testing because results can be hard to interpret and could carry liability if misused. There’s concern patients might pursue unproven treatments based on misunderstood results.

Training

Many doctors don’t run functional tests because they were never trained in them. I’ve worked with clients whose doctors said they couldn’t run stool testing because they weren’t familiar with it. Some even called it a scam, which is hilarious given that much of the current research on digestive health is focused on the microbiome and its connections to just about every area of health. Says more about their interest in learning beyond medical school than it does about the testing.

So the system defaults to basic blood work, “everything’s normal,” maybe an IBS diagnosis if they need to call it something, a recommendation to eat more fiber and manage stress, sometimes a prescription, and out the door. Next patient.

My Experience

I saw six gastroenterologists over the course of about three years. Zero real answers.

The first few gave me the IBS diagnosis and surface-level advice. Eat more fiber, reduce red meat consumption, cut out gluten and manage stress.

So I found the highly recommended specialists. They ran more comprehensive blood work and a colonoscopy. My IBS diagnosis got upgraded to colitis.

Then the investigation stopped.

Every test from that point focused only on inflammation markers. How inflamed was my colon? Was the medication reducing it? That was it.

Meanwhile, I was stuck in a brutal cycle of flare ups. The inflammation was real, but it was downstream. A symptom of something else. Not the thing that needed attention.

I didn’t start making progress until I stopped waiting for doctors to figure it out and ran the testing myself. Comprehensive stool testing alone gave me more answers than I’d gotten over the previous three years.

What I found was a wrecked microbiome, high levels of problematic bacteria, enzyme deficiencies, nutrient deficiencies and other issues directly impacting immune function, inflammation levels and overall digestive health.

None of that showed up in anything my gastros ran. Only the downstream effects.

For the first time, I had specific, measurable, treatable issues. Not a vague diagnosis. Not “manage your symptoms forever.” Actual problems with actual solutions.

Once I addressed them, I got out of the cycle completely.

Breaking Out of the “Everything Is Normal” Loop

If your gut is a mess and you keep being told “everything looks normal,” the problem is likely that they’re not looking in the right places. Same if you’ve been labeled with IBS or told it’s just stress.

The good news is you have options.

There are alternative / integrative practitioners that regularly run the functional testing that conventional doctors often skip. They’re trained to interpret it and actually use the results to guide treatment.

Depending on your location, you can also order many of these tests yourself through direct-to-consumer lab companies like Labify Health, DirectLabs and others. No referral needed.

I’ve helped hundreds of people get relief from gut issues for this exact reason. Not with more surface-level advice or generic protocols. By helping them understand what’s actually going on.

Clients who spent years stuck started improving in weeks. Not because they tried harder. Because for the first time, they knew what they were actually dealing with.

There’s usually a reason you’re not getting better. And it’s probably not something you’ve been investigating or testing for.

When you start looking in the right places, you get answers. And when you have answers, you can finally fix the problem.

If you want to go deeper, I’ve done several posts on functional testing and what they can uncover (read here). I also did a post on ways to get a better understanding of your gut health even without testing (read here).

You deserve more than “everything looks normal” when your symptoms say otherwise.

Most people focus on what they eat. Very few think about the importance of when they eat.

Your gut doesn’t just care about the food. It cares about the timing. And when timing is off, it can cause a lot of issues.

• Bloating that’s worse in the morning despite not eating for hours

• Reflux that only hits certain nights

• IBS that flares without obvious triggers

• Brain fog that doesn’t match your sleep timing or quality

• Food cravings that come out of nowhere

For many people, these trace back to a timing problem that they’ve never considered.

Your digestive system runs on a schedule. When you ignore it, you disrupt the biological systems that determine whether your gut functions properly.

Your Gut Runs on a Clock

Your brain has a master clock driven primarily by light. It tells your body when it’s day and when it’s night. But your gut, liver and pancreas have their own clocks. These peripheral clocks sync to a different signal: food.

When you eat late, you create a timing conflict. Your brain says it’s nighttime (wind down, repair, sleep). Your gut says it’s daytime (digest, absorb, metabolize). This mismatch is much more disruptive than people realize.

Your gut isn’t just “less efficient” at night. The entire digestive landscape shifts:

• Stomach emptying slows: Food sits longer, ferments more, produces more gas.

• Enzyme release changes: You’re not producing the same digestive output at 10pm that you produce at noon.

• Motility drops: The muscular contractions that move food through your intestines are circadian-regulated. Late meals fight against the current.

• Immunity shifts: Your gut immune system has daily rhythms. Circadian disruption tips it toward inflammation.

The same meal eaten at 6pm versus 10pm has significantly different metabolic outcomes. Not because the food changed, because your body’s readiness to process it changed.

Sleep Take a Hit (and your gut pays twice)

Most people think late eating just makes it harder to fall asleep. That’s the surface problem. The deeper issue is what happens to sleep quality even when you do fall asleep.

A randomized crossover study compared routine dinner (about 5 hours before bed) with late dinner (about 1 hour before bed). Late dinner shifted sleep cycles: deeper sleep came earlier, lighter sleep dominated the back half of the night. Same sleep duration, different sleep quality. (PMID: 34017207)

Three mechanisms drive this:

• Nervous system can’t serve two masters: Digestion requires sympathetic activation (the “on” state). Sleep onset requires parasympathetic dominance (the “off” state). When you eat close to bed, you’re asking your body to rev up and wind down simultaneously. The wind-down loses.

• Digestion generates heat at the wrong time: Your body naturally drops its core temperature to initiate sleep. This cooling signal is part of what makes you drowsy. Digestion is thermogenic, meaning it produces heat. Late meals blunt the temperature drop your brain is waiting for.

• Blood sugar and heart rate fluctuations: Large or carb-heavy late meals can trigger brief awakenings you won’t remember but that still disrupt sleep. Your heart rate and metabolic activity spike and dip throughout the night instead of staying stable.

The result is that you sleep, but you don’t recover.

Next-day symptoms include heavier morning grogginess, stronger cravings (especially for quick carbs), and lower stress tolerance. And because gut repair happens primarily during deep sleep, your gut pays for the disruption twice: once from the late meal itself, and again from the impaired recovery window.

Upgrade to Paid

Whenever I look at a client’s stool test, I can tell if they’ve been taking a probiotic supplement long-term.

The pattern is almost always the same: a handful of strains pushed above optimal levels while multiple others sit depleted. And healthy, resilient microbiome balance isn’t there.

This is the opposite of what those supplements promised.

The probiotic industry has convinced millions of people that popping a capsule containing 2-5 bacterial strains will magically increase other strains not found in the capsule and restore overall gut balance. It’s a compelling narrative. It’s also not supported by evidence.

Here’s what most people misunderstand about probiotics, why fermented foods often outperform supplements for microbiome support and when supplements actually make sense.

The Fundamental Problem With Most Probiotic Supplements

Your microbiome depends on dozens of different bacterial strains in a delicate balance. Too little of certain strains creates problems. Too much of others disrupts gut lining integrity, immune function, digestion and other important digestive processes.

Most probiotic supplements contain just a few strains. Even the comprehensive formulas max out at 10-20. Meanwhile, your gut microbiome relies on coordination between far more species than any capsule can provide.

After reviewing countless stool tests, I’ve found that few people have deficiencies in just a couple of specific strains. When people are dealing with imbalances, there are often deficiencies across numerous strains simultaneously. Including many strains you will not find in a probiotic supplement.

If you need 6 specific strains but you’re taking a supplement with entirely different types that you don’t need more of (or might already have too much of), you’re not going to move the needle on what’s actually needed. You’re potentially making imbalances worse by pushing already adequate strains into overgrowth territory.

It’s like adding salt to food without tasting it first. Could make it better. Could also ruin the dish.

What the Research Shows About Probiotic Supplements

Probiotic supplements are marketed as the solution for rebalancing your gut microbiome. Many people believe this is their only option.

But here’s what nobody mentions: there’s no evidence they fully rebalance the microbiome.

They can help in specific situations, which we’ll get to below. But even then, benefits tend to be highly variable, limited to specific probiotic strains and typically disappear the moment you stop taking them.

That’s not restoring balance.

Understanding what probiotic supplements actually do (and don’t do) is the only way to know if they make sense for your situation. So let’s look at what happens when researchers measure real outcomes instead of just asking people how they feel.

Probiotics Don’t Consistently Change the Microbiome

A systematic review analyzed 7 randomized controlled trials using advanced microbiome sequencing to see changes in the composition and activity of the microbiome from probiotic supplementation.

They found no consistent changes in microbiome diversity across all 7 studies. Probiotic supplements didn’t increase richness or shift overall composition in any meaningful way. When changes did occur, they were small, short-lived and highly individualized. (PMID: 27159972)

Another study followed 30 healthy adults taking a single species supplement with Bifidobacterium infantis (1 billion CFU daily) for 30 days. Despite daily supplementation, participants showed no statistically significant increase in Bifidobacterium levels or any other beneficial bacteria. The probiotic passed through without colonizing or affecting the ecosystem.

The Colonization Problem: Stool ≠ Gut

This is where it gets interesting. Most probiotic studies only measure what shows up in your stool. But stool doesn’t necessarily tell you what’s actually happening on your gut lining where colonization needs to happen for lasting benefit.

Colonization means the bacteria actually take up residence in your gut, sticking to the intestinal lining, reproducing and becoming part of your microbiome long-term. Without colonization, probiotics are just tourists passing through.

A study that actually performed colonoscopies and endoscopies on participants (not just stool samples) found that while probiotic strains survived the journey through the gut and showed up in stool, most didn’t actually colonize in the gut mucosa. The majority of people were resistant and their existing microbiome essentially rejected the incoming strains. The probiotics passed through and left the body. (PMID: 30193112)

For the minority who did show temporary colonization, the changes disappeared after they stopped taking the supplement.

This is crucial. Just because you can detect a probiotic strain in your stool doesn’t mean it’s colonizing your gut or reshaping your microbiome.

Probiotics Aren’t Useless, But Context Matters

Before you think I’m anti-probiotic, let me clarify that they can help in specific situations. Certain strains show real benefits for managing overgrowths, calming diarrhea and other acute digestive issues.

But the key word is specific. The research is strain-specific and condition-specific, not “take any probiotic to restore overall gut balance.”

Why Fermented Foods Work Differently

Fermentation was invented out of necessity as a way to preserve food before refrigeration existed. But long after modern food storage made that unnecessary, fermented foods stuck around. People kept making them for the taste and because they noticed real health benefits.

Turns out those benefits aren’t just placebo. Fermented foods offer unique advantages that probiotic capsules can’t replicate. Here’s what makes them fundamentally different from probiotic supplements:

Strain Diversity Supplements Can’t Match

Kefir made with traditional grains can contain 30-50+ different bacterial and yeast species. A single batch of wild-fermented sauerkraut or kimchi can offer 15-30+ strains. Compare that to even the most comprehensive probiotic supplements at 10-20 strains maximum. Most have far fewer.

This diversity matters because your microbiome isn’t a collection of isolated microbes. It’s an ecosystem where different species interact, compete and support each other.

They are all important and play different roles. Flooding that system with massive quantities of just a handful of specific strains is fundamentally different than introducing a diverse group of microbes.

The Food Matrix Advantage

Here’s something else fermented foods provide that most capsules don’t: the complete food matrix and synergistic nutrients.

Dairy fats in fermented dairy help protect bacteria during transit and improve colonization. Fermented vegetables provide fiber and prebiotics that both transport bacteria through the gut and feed them once they arrive.

Beyond just delivering microbes, many fermented foods provide nutrients that support gut function directly. Micronutrients for immunity and motility from vegetables, bioactive peptides and proteins from dairy. The fermentation process itself can also make these foods easier to digest by breaking down antinutrients, predigesting lactose and casein as well as improving nutrient absorption.

Most supplements don’t offer any of this. Survival depends entirely on capsule technology, and most standard capsules dissolve before bacteria reach where they’re needed. Enteric coated capsules help, but this is something that whole foods handle naturally.

CFU Reality Check

There’s a common assumption that supplements deliver more bacteria. Not necessarily true.

• Kefir: 15-30 billion CFU per cup

• Yogurt: 10-30 billion CFU per cup

• Fermented vegetables: 5-50 billion CFU per serving (highly variable)

• Probiotic supplements: 1-15 billion CFU standard, 30-50 billion in premium products

These ranges vary based on brand, storage and fermentation process. But the assumption that supplements deliver far more bacteria than food isn’t accurate. Many fermented foods match or exceed supplement CFU counts, with significantly more diversity and often at a fraction of the cost.

Another thing most people don’t realize is that many probiotic supplements list CFU count at the time of manufacture, not at expiration. By the time you’re actually taking them, those numbers may be significantly reduced.

Some quality brands guarantee counts through expiration but many don’t specify.

For example, Culturelle explicitly states the CFU on their label is guaranteed through the expiration date. Seed on the other hand uses AFU (active fluorescent units), which focuses on delivery technology, but does not clarify whether the listed count reflects amounts at expiration or that they guarantee these levels throughout the shelf life. This is worth noting, especially considering that Seed is also one of the most expensive probiotics on the market.

The Stanford Study That Changed the Conversation

In 2021, Stanford researchers published a great study on this (PMID: 34256014). They directly compared two dietary interventions in 36 healthy adults over 10 weeks: high fermented foods (gradually increased to 6 servings daily) versus high fiber (increased to ~45g daily).

Fermented foods steadily increased microbiome diversity across the entire study period. This was cohort-wide, not just in a few responders. The more fermented foods consumed, the higher the diversity.

The fermented food group also showed significant decreases in 19 inflammatory markers, including IL-6, a key driver of chronic inflammation.

This is one of the only large-scale interventional trials on fermented foods using high-resolution sequencing, which is the testing that actually measures microbiome-wide changes rather than just tracking a few bacterial species.

When Supplements Make Sense

I’m not arguing that probiotic supplements are useless. I use them. They have advantages in specific situations:

Antimicrobial Support for Overgrowths

When dealing with SIBO, candida, H. pylori or other overgrowths, certain probiotic strains can help. A systematic review of 18 clinical trials found SIBO was cleared in ~53% of cases using probiotics (varying based on strain, dose and condition), which was comparable to the antibiotic rifaximin. (PMID: 28267052) Specific strains like Lactobacillus casei and Saccharomyces boulardii have shown benefits for clearing overgrowths and calming diarrhea. (PMID: 38337613, PMID: 38542689)

Diarrhea (including antibiotic-driven diarrhea)

Multiple studies show that Saccharomyces boulardii and Lactobacillus rhamnosus GG (LGG) can help resolve diarrhea. In randomized trials and meta‑analyses, S. boulardii reduced diarrhea duration by ~1-2 days and lowered antibiotic‑driven diarrhea risk by ~40-60%, while LGG shortened diarrhea by ~24 hours on average and reduced antibiotic‑driven diarrhea by ~30-50% when taken during antibiotic use. (PMID: 22423260, PMID: 38286962, PMID: 31543689)

Addressing Specific Deficiencies (identified through testing)

If stool test shows specific strains are low, targeted supplementation with quality brands containing those strains may be helpful short-term. This requires knowing what you’re actually deficient in, otherwise you’re guessing. And it’s important to keep in mind that studies showing probiotics can increase specific strains also show these benefits don’t last after supplementation stops.

The important distinctions here:

• Probiotics appear to be more useful for managing specific conditions or symptoms than for broadly increasing all bacteria levels, restoring overall balance or improving long-term microbiome diversity.

• There is no evidence that improvements from probiotic supplements are permanent. Research consistently shows benefits are short-lived and do not last after supplementation stops.

The Quality Problem

If you do use supplements, quality matters. Multiple studies have exposed issues worth noting:

29 probiotic products found that many contained far fewer live organisms than stated on their labels, with some delivering anywhere from just 7% to just over half of the claimed CFU count at purchase, and only 2 of 13 independently tested products accurately met label claims.

An analysis of 50 widely used U.S. probiotic supplements found that around one‑third of products did not fully match the label claims. The study also detected antibiotic-resistant genes in nearly all products (90%), raising concerns about infections that are resistant to treatment. (PMID: 38856022)

When you’re paying $60+ per month for a probiotic, you need confidence that you’re getting what the label claims.

What To Do With This

So where does this leave us?

If you want general microbiome support and don’t have testing: Fermented foods are often a good place to start. Foods like kefir, yogurt, sauerkraut, kimchi or any fermented veggies. They provide more of the diversity your gut needs without the risk of overloading strains you don’t actually need more of and promoting imbalances. Beginning with one serving a few times a week and working up to daily can help with tolerance.

One note: if you’re dealing with histamine intolerance, fermented foods may be hard to tolerate initially. In that case, focusing on dietary fiber may be the better starting point while you address the underlying issues driving histamine intolerance.

If testing shows specific deficiencies: Targeted supplementation with quality brands can help, but is often best paired with fermented foods and dietary fiber. Studies consistently show probiotic benefits don’t persist after you stop taking them, so pairing supplementation with fermented foods and prebiotics (which support the broader ecosystem, not just isolated strains) may help promote better long-term results.

If you’re taking antibiotics, dealing with overgrowths or having bowel movement issues: This is where probiotics have the strongest evidence. Using specific strains for specific purposes like Saccharomyces boulardii during antibiotic treatment can be great short-term support.

If you’ve been struggling and nothing seems to stick: Consider functional testing like a comprehensive stool test, OAT, blood work, etc. If you’ve tried multiple supplements without lasting improvement, confirming what is actually going on can change everything. You can’t know exactly what you need until you know what’s wrong.

The real issue isn’t that probiotics are bad. It’s how they’re marketed. They’re sold as a universal gut health solution when the evidence says otherwise. Different strains serve different functions in different amounts. Targeted beats guessing every time.

Many gut issues people struggle with are extremely treatable once you provide the specific support your gut actually needs. Adding random probiotic supplements without any clue what’s going on often just leads to spending a lot of money without anything to show for it.

Upgrade to Paid

Most people with chronic gut issues have tried dozens of supplements that didn’t work.

I was one of them. I had a graveyard of random things from social media threads. Some did nothing. Some made things worse. A few helped briefly, then stopped.

The problem wasn’t the supplements. It was using them without understanding what I actually needed.

Chronic gut issues are rarely simple. What starts as one thing becomes several things. Multiple contributing factors, overlapping issues, downstream effects throughout the body.

Generic advice like “just take a probiotic” almost never cuts it.

Two things changed my results:

First, getting clarity. You can’t know what supplements you need until you know what’s actually wrong. Without looking deeper than surface-level symptoms and running testing to get a real understanding of your situation, you’re guessing. Which is why most people end up with a cabinet full of supplements that never helped.

Second, covering the basics. If your diet is a mess, you’re not sleeping, you’re chronically stressed, you’re never exercising and you never see the sun, supplements won’t save you. These are prerequisites, not optional.

Once those pieces were in place, targeted supplements accelerated my progress in ways that would have been difficult or impossible otherwise.

That’s what this post covers: the 10 supplements that had the most noticeable impacts for me, what they’re actually useful for and why they helped in my specific situation.

Context matters. If your situation is different, the supplement might not apply to you.

Taurine

Taurine is an amino acid that plays a key role in bile acid conjugation, the process of attaching taurine (or glycine) to bile acids so they can function properly.

Bile directly impacts fat digestion, antimicrobial defenses in the small intestine, toxin clearance and hormone elimination. It’s also plays a role maintaining microbiome balance in your gut. When bile flow is slowed or the composition is off, you often see poor fat digestion, overgrowths and a backup of toxins and hormones that should be leaving the body.

Beyond bile, taurine stabilizes mitochondrial membranes, reduces oxidative stress and supports signaling that promotes your “rest and digest” state and gut motility.

Because of these effects, taurine can help in many situations. It’s especially relevant for SIBO, poor fat digestion, toxin exposure, gallbladder issues, mast cell issues and neurological-related gut issues.

What I noticed: Improved fat digestion was the clearest change. I had been dealing with greasy, light-colored stool and that heavy feeling after eating fats. With taurine, stool improved, I felt calmer after meals, bloating decreased and I had a subtle improvement in energy and mental clarity, especially in the late afternoon.

Zinc Carnosine

Zinc carnosine uniquely binds to damaged areas of your stomach and intestinal lining. Once bound, it stimulates cell regeneration, repairs tight junctions (the seals between cells that prevent leakage) and reduces local inflammation.

Unlike standard zinc supplements, zinc carnosine concentrates specifically where healing is needed without disrupting your microbiome. It also has antimicrobial activity against H. pylori and helps stabilize mast cells, which can reduce histamine-driven reactions like bloating, urgency and skin flushing.

Because of these effects, it can be extremely helpful for leaky gut, reflux, ulcers, gastritis and histamine sensitivity.

What I noticed: I used zinc carnosine when dealing with leaky gut. I had a constant inflamed feeling, extreme food sensitivity and discomfort on an empty stomach. Within days (days, not weeks), these improved noticeably. Not gone overnight, but noticeable and sustainable improvement.

Butyrate (Sodium or Tributyrin)

Butyrate is a short-chain fatty acid and the primary fuel source for colonocytes, the cells lining your colon. It’s also a key regulator of gut lining integrity, immune tolerance and inflammation control.

Butyrate strengthens tight junctions, increases intestinal alkaline phosphatase (an enzyme that neutralizes bacterial toxins that commonly drive inflammation) and supports vagus nerve signaling, which controls the communication between your gut and brain. It also supports serotonin production in the gut.

The tributyrin form delivers butyrate further down the digestive tract to the colon, rather than being absorbed earlier.

These effects make butyrate helpful in many situations, particularly autoimmune gut issues like IBD, leaky gut, dysbiosis and gut-brain axis issues.

What I noticed: I used butyrate when dealing with IBD and leaky gut. What I noticed most was less reactivity to foods, less discomfort between meals and less anxiety.

Thiamine (Benfotiamine and TTFD)

Thiamine (vitamin B1) drives mitochondrial energy production, the ATP your cells need to function. This is critical for motility, gut lining repair and nervous system regulation in the gut.

There are two forms worth knowing:

Benfotiamine is fat-soluble, so it enters cells more effectively than regular thiamine. It’s particularly useful for cellular energy, blood sugar regulation and nerve function throughout the body, including the gut.

TTFD crosses into the central nervous system more effectively. It supports vagal tone (the activity of the vagus nerve that controls digestion and relaxation) and helps detoxify aldehydes, toxic byproducts that build up from candida, mold and other exposures.

Without enough thiamine, digestion, motility, detoxification and nervous system regulation are commonly disrupted.

What I noticed: Benfotiamine gave me steady daytime energy, helped reduce sugar crashes and more regular bowel movements. TTFD had a noticeable effect on motility and made me feel more stable overall.

Herbal Antimicrobials

One of the most common issues I see in clients is overgrowths: bacteria, yeast, parasites. These drive inflammation, destabilize immune function, weaken the gut lining and disrupt digestion.

Conventional medicine almost always reaches for antibiotics or prescription antifungals. These can work, but they don’t effectively break up biofilms (protective shields microbes hide behind), many microbes are resistant to them and many of them wipe out beneficial bacteria along with the harmful ones. This often leaves people vulnerable to overgrowths again within weeks.

Herbal antimicrobials work through multiple mechanisms, making it difficult for microbes to develop resistance. They’re also selective, preserving beneficial bacteria and in some cases even promoting their growth. This supports rebalancing rather than nuking the gut and clearing everything in its path. I’ve found them far more effective without the common downsides of prescription antimicrobials, which several studies have shown as well.

Effective options include things like black walnut, mastic gum, olive leaf extract, neem, berberine, garlic, black seed, caprylic acid and oregano.

What I noticed: I’ve successfully used all of these. In the short-term, you can feel worse as microbes die off and release toxins. This is why preparation (supporting motility, drainage, detox) is often crucial along with binders. But when used correctly, these can be extremely effective. I went from chronic bloating, pain, brain fog and fatigue to feeling completely normal once the overgrowths cleared.

Glycine

Glycine is the simplest amino acid but has broad effects. It supports glutathione production (your body’s master antioxidant), liver detoxification, bile production, collagen production for gut lining repair and methylation (the process your body uses to activate nutrients, produce neurotransmitters and clear toxins).

It also calms the nervous system, promoting the “rest and digest” state and improving sleep quality.

Glycine can be helpful for issues like detox overload, chronic inflammation, gut lining repair, mold recovery and nervous system-driven digestive issues.

What I noticed: Deeper sleep, calmer gut and a noticeably higher baseline for stress tolerance. There was a general soothing effect, like my nervous system had more capacity.

Colostrum

Colostrum is the first milk produced by mammals after giving birth. It provides immune protection through immunoglobulins, which are antibodies that help your immune system identify and neutralize harmful invaders. It also has growth factors for gut lining repair and compounds that help recalibrate overactive immune responses.

Colostrum supports beneficial microbes and helps your immune system recognize food as safe rather than triggering a reaction. It also provides lactoferrin, which helps defend against harmful microbes and supports iron regulation.

What I noticed: I used colostrum while dealing with leaky gut and microbiome imbalances. I noticed fewer food sensitivities and less overall gut discomfort. I’ve also used it when healthy for general gut and immune support.

Magnesium Glycinate

Magnesium is involved in over 300 enzyme reactions. For gut health, it supports motility (keeping things moving), relaxes smooth muscles, improves stress resilience and activates enzymes needed for digestion and detox.

It also promotes DAO activity, the enzyme that breaks down histamine, which is helpful for people dealing with histamine issues. And it calms the network of nerves in your gut that controls digestion.

The glycinate form is particularly good because the glycine adds a calming effect, it absorbs well and it doesn’t pull fluids into the colon like citrate or oxide, making it a better option for people dealing with loose stool or urgency.

What I noticed: Significant improvement in sleep and improved stress tolerance.

Digestive Enzymes

Digestive enzymes help break down proteins, fats and carbohydrates into absorbable nutrients. Your body should do this naturally, but often doesn’t when dealing with digestive issues. This can happen due to age, stress, low stomach acid, inflammation or other gut issues.

When food isn’t properly broken down, it leads to nutrient malabsorption and leaves behind undigested material that can cause excessive fermentation (gas, bloating), feed overgrowths and drive irritation.

A full-spectrum digestive enzyme typically includes proteases (for proteins), lipases (for fats), amylases (for carbohydrates) and sometimes betaine HCl or ox bile for additional stomach acid and fat emulsification support.

What I noticed: Immediate improvement in digestion with much less bloating and discomfort after meals. After consistent use, I noticed improvements in energy and cognition from better nutrient absorption.

Boswellia

Boswellia is a resin extract best known for inhibiting 5-LOX, an enzyme that produces inflammatory compounds heavily involved in gut inflammation, especially in conditions like colitis and crohn’s.

Unlike NSAIDs, which reduce inflammation but often damage the gut lining, boswellia reduces inflammation without harming the gut. It also helps stabilize mast cells, making it useful for calming histamine-related symptoms like bloating, urgency and cramping.

Extracts standardized to AKBA (the most active anti-inflammatory compound in boswellia) are most effective. Not all boswellia supplements provide effective levels, so this matters when choosing a product.

What I noticed: I used this while dealing with colitis. I had a noticeable reduction in inflammation and pressure in my lower abdomen within weeks. This was one of the most effective natural anti-inflammatory supplements I’ve used.

Final Thoughts

These supplements gave me noticeable improvements because I used them to address specific issues I had confirmed I was dealing with. They won’t be broadly effective for every gut issue, but can be very helpful in the situations mentioned.

The key is understanding your situation first, then choosing tools that actually make sense. Without that clarity, you end up guessing and can waste a lot of money and time on things that aren’t relevant to your situation.

Foundations always come first: diet, sleep, stress, movement, light environment, etc. But with chronic gut issues, these alone are often not enough. That’s where targeted supplementation can make a huge difference.

I’ve worked with hundreds of people who spent years and hundreds if not thousands of dollars trying to fix their gut.

The reason most of them stayed stuck had nothing to do with effort. They were trying to solve the wrong problems.

Elimination diets, probiotics, digestive enzymes, apple cider vinegar, low FODMAP and maybe even a round or two of antibiotics that your gastroenterologist promised would finally knock out the SIBO (despite the multiple failed attempts).

None of it worked. Not because these things can’t help. Because they weren’t addressing what was actually going on.

If that sounds familiar, you already know what I’m talking about. Still bloated. Still exhausted. Still planning your life around bathroom access and food restrictions that don’t even seem to help consistently.

The truth is, you probably don’t need another general protocol or supplement. I’ve seen too many people burn through money chasing symptoms while the actual problems silently get worse.

I’m not going to promise that some magic supplement or 3-day cleanse is going to fix years of dysfunction. That’s not how this works.

This is an overview of some of the most important things you can focus on right now to start building stability and actually understand what’s going on in your body. Not another generic protocol. Not more guessing. Just the foundations that most people skip over while chasing the next shiny peptide.

By following these steps, I’ve seen people make more progress in weeks than they had in years.

The Real Reason You’re Not Getting Better

A lot of gut health advice is useless to the people reading it. It’s generic and not relevant to their situation. Generic advice doesn’t properly address problems that vary from person to person.

“Do the low FODMAP diet” But what if you tolerate many high-FODMAP foods just fine?

“Take a probiotic” Which strain? For what imbalance?

“Eat more fiber” But what if fiber makes your symptoms 10x worse right now?

The biggest reason so many people haven’t made real progress despite trying so many things to improve their gut health is that they don’t know what’s actually going on. Most of the things they’ve been doing likely aren’t addressing the right things.

If you don’t know what is wrong and what is causing those problems, you’re not going to know what you need to do. You can try all of the diets, supplements or protocols you want, but if they’re not addressing the correct things, they’re not going to make a difference.

You don’t get results based on effort. You get results from providing your gut with what it actually needs.

Two people could have the exact same symptoms. But those symptoms could be caused by entirely different issues. And even two people dealing with the same larger issue, let’s say SIBO as an example, could have entirely different things causing that to happen.

Same symptoms or diagnosis. Different issues involved. Different fixes.

You can’t solve what you don’t understand. And you can’t understand what you’ve never actually investigated.

This is the biggest reason why so many people stay stuck for years. They cycle through protocols and practitioners, each one offering a new theory and a new stack of supplements, but nobody stops to actually confirm what’s happening.

The first step to fixing your gut isn’t an intervention. It’s getting clarity.

The Self-Sabotage Trap

If you’ve been dealing with chronic gut issues for years, especially something like IBS that doctors have told you is “just something you’ll have to manage,” there’s a decent chance you’ve internalized a belief that’s silently sabotaging everything you try.

The belief that you’re broken. That your body is fundamentally defective. That healing, real healing, isn’t actually possible for you.

This becomes self-fulfilling.

When you believe deep down that you can’t actually get better, every decision becomes less serious. You cheat on your diet because “it probably won’t matter anyway.” You skip the sleep. You don’t bother tracking symptoms because “what’s the point.” You half-commit to protocols because some part of you has already decided they won’t work.

I’ve seen this pattern hundreds of times. Someone comes to me after years of failed attempts, convinced they’re just uniquely broken. Then we start looking deeper, find the actual issues, address them systematically and suddenly this “incurable” person is living a normal life again.

Gut issues aren’t your identity. They are problems with causes. And problems with causes have solutions.

But you have to actually believe that healing is possible before you’ll do the work required to make it happen.

Symptom Whac-A-Mole

Most gut health advice operates at the wrong level.

Bloated? Here’s an enzyme. Constipated? Here’s magnesium. Reflux? Here’s something to neutralize the acid.

These tools can be helpful. But when they’re used on their own as the solution, they only provide temporary relief because they’re typically addressing downstream effects, not upstream causes. And when you only treat effects, the causes continue to fester and usually get worse over time.

This is why people end up on PPIs for years while their stomach acid drops lower and lower, creating the conditions that feed issues like bacterial overgrowth, which can directly contribute to the reflux they’re trying to solve.

It’s why people take Imodium for decades while the motility issues causing their symptoms never get addressed.

It’s why someone can spend thousands of dollars on supplements that manage symptoms without ever actually healing.

The gut is a system. When something goes wrong, it creates cascading effects throughout that system. If you only intervene at the symptom level, you’re playing whack-a-mole forever.

Real healing requires asking different questions entirely.

• Is stomach acid sufficient to sterilize incoming food and microbes?

• Is motility strong enough to sweep bacteria and debris through the system?

• Is the gut lining intact or are things leaking into the bloodstream that shouldn’t be there?

• Is the microbiome balanced or has something taken over that doesn’t belong?

• Are bile production and flow functioning properly for fat digestion and detox?

These are the types of questions that actually lead somewhere. But most people have never even considered them. Instead, they get generic advice that doesn’t apply to them or band-aids to manage symptoms.

The One-Week Protocol

What follows is an overview of adjustments and focuses that will give you more clarity and stability with your gut health than many people get in years of trying to solve gut issues.

This is not about making dramatic changes that you’ll abandon in a week. It’s about gradually making adjustments and finally understanding what’s actually happening so that every decision you make going forward is focused on the right things.

Day 1: The Audit

Before you change anything, you need to better understand your starting point.

Most people have a vague sense that their gut isn’t great, but they’ve never actually mapped out what’s happening. They can’t see patterns because they’ve never documented them.

Get out a notebook or open a notes app. Work through these questions honestly.

The Timeline

• When did your gut issues actually start? Not when they got bad. When did you first notice something was off?

• What was happening in your life at that time? Infection? Antibiotics? Major stress? Found mold in your house? Travel? Food poisoning?

• How have symptoms evolved since then? What’s gotten better? What’s gotten worse? What’s new?

The Current State

• What are your primary symptoms right now? List them all: bloating, gas, pain, reflux, constipation, diarrhea, brain fog, fatigue, skin issues, mood issues.

• Rate each symptom 1-10 in severity.

• When do symptoms typically occur? After meals? Specific times of day? Related to stress?

• What patterns have you noticed? Foods that trigger issues? Activities that make things better or worse?

The Honest Inventory

• What are you currently eating or drinking that you know probably isn’t helping? Don’t rationalize. Just list it.

• What lifestyle factors might be contributing? Sleep, stress, lack of movement?

• What have you tried that seemed to help, even temporarily?

• What have you tried that made things worse?

The Deeper Questions

• Do you actually believe you can heal? Or has some part of you accepted this is just your life now?

• What would it mean for your life if these issues were resolved? What would become possible?

• What would it cost you to stay exactly where you are for another five years?

Take your time with this. The goal is clarity on your starting point.

Days 2-6: Elimination, Observation and Tracking

Now we move from reflection to action.

For the next six days, we’re going to eliminate the most common gut irritants and carefully observe how your body responds. This isn’t a permanent diet. It’s giving your gut a break while you pay attention to what changes.

What to Remove:

• Refined sugar (feeds problematic bacteria/yeast/parasites, promotes inflammation)

• Seed oils (canola, soybean, corn, safflower, sunflower, grapeseed)

• Gluten (bread, pasta, baked goods, anything containing wheat/barley/rye)

• Conventional dairy (A1 dairy, factory-farmed and high-lactose products like milk, cream and soft cheeses are usually most problematic. If you tolerate A2 dairy like ghee or butter, those are usually fine)

• Alcohol (completely)

• Coffee (highly acidic and irritating for many)

• Processed food additives (polysorbate 80, carrageenan, sodium benzoate, BHA, BHT, sodium nitrate)

• Artificial sweeteners (aspartame, sucralose, acesulfame potassium)

• Raw vegetables (cook everything for now, it’s easier to digest)

• Nuts and seeds (not inherently bad, contain antinutrients, poor omega-6:3 ratios and can be difficult when the gut is compromised)

• Tap water (often contains chlorine, heavy metals, prescription drugs and other compounds that disrupt the gut)

• Unnecessary stress (doom scrolling, “news” cycles, being disorganized)

• Non-organic produce (pesticides affect the microbiome. At minimum, avoid the “Dirty Dozen”)

These aren’t all necessarily permanent. The goal is removing common irritants to establish some stability while you gather data.

There may also be other foods not listed here that trigger symptoms for you personally. If you consistently notice a clear connection between a specific food and a symptom flare, it’s likely best to pull it out for now even if it’s considered “healthy” or normally well-tolerated.

Prioritize foods that support the gut:

• Simple, whole foods your great-grandmother would recognize

• Cooked vegetables (easier to digest than raw)

• Quality animal protein (pasture-raised, grass-fed, wild-caught when possible)

• Bone broth (skip if you react to histamine)

• Stewed fruits and antioxidant-rich foods like blueberries

• Fermented foods if you tolerate them (start small)

• Prebiotic foods like chicory root, garlic, carrots, oats, okra

• Protective herbs like licorice, marshmallow root, slippery elm

• Cooking fats like tallow, butter, ghee, olive oil, coconut oil

• Filtered, spring or mineral water with a pinch of salt for proper hydration

Not all of these will work for everyone. Tolerances vary. But these are foods that generally support a healthy gut.

Meal Timing and Habits

Timing

Eat only during daylight hours and maintain at least 3 hours between meals (no snacking). This allows your gut’s cleaning process (MMC) to actually do its job. Constant snacking means this process never completes.

Before eating

Practice deep breathing exercises like box breathing: 4 seconds in, 4 seconds hold, 4 seconds out, 4 seconds hold. This shifts you into parasympathetic mode before you eat. You cannot digest well when your nervous system is in fight-or-flight.

After eating

Walk for 10-15 minutes (this supports gastric emptying and motility better than almost anything else). Don’t lay down or sit at a desk immediately after meals.

The Tracking

This is where most people fail. They make changes but never track what happens, so they never learn anything useful.

Track as much as you can. More data means better understanding of what you’re actually dealing with.

Bowel movements (every time):

• Time of day

• Bristol Stool Scale rating (1-7, look it up if unfamiliar)

• Effort and pain level

• Complete or incomplete feeling

• Presence of gas, mucus or undigested food

• Unusual odor (can indicate bile issues, fermentation or infection)

Symptoms (check in every few hours):

• Current symptoms rated 1-10

• Energy level (1-10)

• Mental clarity (1-10)

• Stress level (1-10)

• What you ate in the previous 2-3 hours

• Any significant events or stressors

What you’re looking for:

• Do symptoms correlate with specific meals or timing?

• Does the 3-hour meal spacing change anything?

• Does walking after meals make a difference?

• Does eating simpler foods change your bowel movements?

• How do symptoms on day 5 compare to day 2?

A week of careful tracking teaches you more about your body than months of casual observation.

The Environment Reset

While tracking food and symptoms, you’re also resetting the environmental factors most people ignore.

Morning:

• Get outside within the first hour of waking

• Direct sunlight through eyes for at least 10 minutes (not through a window, no sunglasses)

• This sets your circadian rhythm, which governs almost every digestive process

Throughout the day:

• Natural light exposure when possible

• Breaks outside, especially around midday

• Movement every hour or two (even 5 minutes of walking or stretching)

Evening:

• Reduce artificial light after sunset

• Night mode on devices at minimum, blue-light blocking glasses if possible

• Stop eating at least 3 hours before bed

Sleep:

• 7+ hours every night

• Cool, completely dark room

• Consistent bed and wake times

• Unwind before bed: brain dump before bed, read, pray, meditate, etc.

Day 7: Review

You’ve spent a week paying close attention to your body, eliminating common irritants and tracking what happens.

Now it’s time to synthesize what you’ve learned.

Review Your Data:

• Look at your tracking. What patterns appeared?

• Did symptoms improve, worsen or stay the same?

• How did day 6 compare to day 2?

Get Clear on the Stakes

Write this out. Don’t just think about it.

What does your life look like if nothing changes for the next 3 years?

• The social events you’ll keep avoiding because of unpredictable symptoms

• The career impacts from brain fog, fatigue and lack of confidence

• The relationships affected by your inability to travel or eat out freely

• The long-term health consequences of unresolved gut issues

• The costs of doctor visits, supplements and failed approaches continuing to accumulate

• The identity of “the person with gut issues” solidifying further

What becomes possible if you actually resolve these issues?

• Waking up with energy instead of dragging yourself through the morning

• Eating at a restaurant without analyzing every ingredient

• Traveling without your health dictating every decision

• Mental clarity to actually show up for your career, relationships and life

• Feeling comfortable and confident in your body again

• Saying yes to things you’ve been saying no to for years

The Clarity Document

Based on everything from this week, write out:

• Your primary symptoms ranked by severity and impact

• Likely contributing factors from your notes (diet, lifestyle, stress, sleep)

• Patterns and triggers you identified from tracking

• What needs further investigation (potential root causes, testing that might make sense)

• What must change going forward

• What you’re committing to for the next 30 days

Where You Go From Here

You now have something most people with chronic gut issues never achieve: some clarity on your actual situation.

The biggest roadblock for most people isn’t effort or the wrong supplements. It’s that they have no idea what’s actually going on. They’re making decisions in the dark and wondering why nothing works.

Doing these things above helps change that.

But one week doesn’t undo years of issues. This is a starting point, not a finish line.

The good news: most of these habits stack together and take almost no effort once they’re routine. Morning sunlight and movement happen at the same time. Breathing exercises take a few minutes before meals. Consistent sleep timing isn’t extra work, it’s just doing what you already do on a schedule. The food changes aren’t deprivation. You’re swapping what you eat, not eating less.

What Comes Next

Some people uncover clear patterns within a week. Others need two or three weeks. The goal is understanding, not speed.

As patterns appear, you may identify specific trigger foods that need to come out. You may find that testing makes sense: comprehensive blood work, SIBO breath test, comprehensive stool test, organic acids, etc. The data you’re gathering can help point you toward what testing is actually relevant rather than throwing money at random tests hoping something shows up.

This process does two things:

• You start understanding what’s actually going on

• You stabilize things by removing common contributors and adding habits that support healing.

This foundation is what everything else builds on.

Taking Back Control

The end goal isn’t managing symptoms forever. It’s resolving the underlying issues.

A lot of people get on an elimination diet, feel better and just stay there. But elimination alone doesn’t fully resolve most common gut issues. It just removes triggers. The deeper causes of sensitivities are still there.

This is why symptoms often return the moment someone tries to reintroduce perfectly healthy foods. Garlic isn’t the problem. The problem is unaddressed issues that make those foods intolerable.

Same with supplements. Stacking random products to manage symptoms doesn’t resolve anything. Targeted supplements that address specific issues you uncover can absolutely help. But you have to know what you’re addressing first.

This is the difference between managing and resolving. Managing means avoiding triggers and taking things to keep symptoms at bay. Resolving means identifying the actual dysfunction and fixing it so those triggers stop being triggers.

That shift isn’t just physical. It’s also mental.

Part of healing means separating yourself from the identity of being broken. You’re not “the person with incurable gut issues.” You’re a person dealing with problems that have causes. And problems with causes have solutions.

If you’ve been dealing with this for a long time, realistic expectations matter. This won’t resolve overnight. It takes time and consistency. But if you stay with these foundations over months, do the deeper work through testing and make targeted changes based on what you find, it can change everything.

I’ve been there.

This process helped me to eliminate all symptoms and signs of my autoimmune disease. I have no ongoing issues and live a completely normal life again.

That’s what’s possible when you stop managing and start resolving.

After 35 years of evidence, the FDA finally banned Red Dye No. 3 from the American food supply.

The reason was that it causes thyroid cancer in animals and falls under the Delaney Clause, a 1960 law that prohibits any food additive shown to cause cancer in humans or animals (PMID: 2824305).

But let’s be clear, this wasn’t new information. The cancer link has been known since the 1980s. They banned Red 3 from cosmetics in 1990 because it was too dangerous to put on your skin. But eating it? That was fine for another 35 years.

Now HHS and the FDA have announced plans to phase out all petroleum-based synthetic dyes. Six dyes that are currently in thousands of products that millions of people buy: Blue 1, Blue 2, Green 3, Red 40, Yellow 5 and Yellow 6.

This isn’t fearmongering. It’s finally an acknowledgement that common processed food ingredients are not safe for humans to consume. The same companies selling products here with dyes have been selling dye-free versions in Europe for over a decade. Same product. Different standards.

That’s about to change.

What Are Artificial Food Dyes

Let’s start with the basics.

Artificial food dyes are synthetic chemicals derived from petroleum. Yes, the same base material used to make gasoline, plastics and industrial solvents. They were originally created from coal tar in the late 1800s and have over time transitioned to chemically synthesizing them from petroleum.

The reason they exist is purely cosmetic. They make food look more appealing. They compensate for natural color loss during processing, storage and light exposure. They create that artificial “bright” look that grabs your attention on store shelves.

That’s it. There is zero nutritional value. None. Which is why it is comical to see people go to extreme lengths to argue that removing them is wrong (purely political and due to who is behind this).

What they do come with is a chemical structure your body was never designed to process. These aren’t plant pigments like the anthocyanins in blueberries or the beta-carotene in carrots. They’re industrial chemicals that happen to reflect light in ways our eyes perceive as color.

The FDA’s History With Food Dyes

Here’s what most people don’t realize about FDA approval: it doesn’t mean “proven safe.” It means “not proven dangerous enough to ban yet.”

The FDA currently allows eight synthetic dyes for use in food (down from nine, now that Red 3 is banned):

• Blue No. 1 (Brilliant Blue)

• Blue No. 2 (Indigo Carmine)

• Green No. 3 (Fast Green)

• Red No. 40 (Allura Red)

• Yellow No. 5 (Tartrazine)

• Yellow No. 6 (Sunset Yellow)

• Citrus Red No. 2 (only for orange peels)

• Orange B (technically approved but no longer used)

Many of these have been banned, restricted or require warning labels in other countries. The European Union has required warning labels on foods containing these dyes since 2010, stating they “may have an adverse effect on activity and attention in children.”

Some companies (Mars, Kellogg’s, McDonald’s, Kraft) already removed synthetic dyes from their products sold in the EU. But the same products sold in the U.S. are still full of them.

Until now.

The Carcinogen Problem

Three of the most commonly used dyes (Red 40, Yellow 5, Yellow 6) have been found to be contaminated with benzidine. Benzidine is a known human carcinogen, linked specifically to bladder cancer in occupational studies going back to the 1920s.

The FDA calculated in 1985 that consumption of free benzidine raises lifetime cancer risk to just below their “concern” threshold of 1 in 1,000,000 people. So they allowed it under that limit.

Researchers have since pointed out that these dyes can also contain bound forms of benzidine in higher amounts. These forms were not adequately measured in the FDA’s standard testing at the time. These bound compounds can be broken down by enzymes in the body, releasing additional benzidine later. This exposure wasn’t fully accounted for in the FDA’s original review.

A 2012 review looked at all nine FDA-approved dyes and concluded that all of them raise health concerns of varying levels. Three dyes were found contaminated with benzidine or other carcinogens. Red 3 was shown to cause cancer in animals. Multiple dyes showed damage to DNA (PMID: 23026007).

Red 40, specifically, has been found in research to cause DNA damage, intestinal inflammation and disrupt the p53 tumor suppressor pathway, which is the same pathway that helps prevent cancer and is mutated in about 50% of all human cancers (PMID: 37719200).

The Behavioral Effect Is Real

This is where the evidence is actually strongest and where the FDA has historically been most resistant.

In 2007, a study changed the conversation. It was a randomized, double-blind, placebo-controlled trial involving nearly 300 children from the general population, not kids pre-selected for behavioral problems (PMID: 17825405).

The results showed that mixtures of artificial food colors and sodium benzoate significantly increased hyperactive behavior in both 3-year-olds and 8 to 9-year-olds. The effect wasn’t limited to kids with ADHD. It affected children across the behavioral spectrum.

The UK’s Food Standards Agency responded by recommending the removal of six artificial dyes from food. The European Union mandated warning labels.

The FDA held an advisory committee meeting in 2011, acknowledged the evidence and decided not to act.

A 2021 report from California’s Office of Environmental Health Hazard Assessment reviewed all available evidence (27 clinical trials and multiple animal studies). Their conclusion was that synthetic food dyes are associated with adverse neurobehavioral outcomes in some children, and the FDA’s acceptable daily intake levels are based on studies 35-70 years old that weren’t designed to detect behavioral effects.

In some children, the effect occurs at intake levels below what the FDA considers safe.

Research suggests artificial dyes may affect behavior through several pathways:

• Histamine release in sensitive children

• Changes in neurotransmitter levels

• Interactions with nutrient absorption

• Changes in the gut microbiome

What Happens In Your Gut

The emerging research on food dyes and gut health definitely raises concerns.

A 2022 study looked at the effects of Red 40 on gut health in mice. Long-term exposure involved:

• Triggered chronic low-grade intestinal inflammation

• Disrupted the gut lining (increased intestinal permeability, aka leaky gut)

• Shifted composition of the gut microbiome

• Increased susceptibility to colitis

The mechanism appears to be serotonin. The dye increased serotonin levels in the colon, which downregulated gut lining proteins, shifted the microbiome and increased susceptibility to inflammatory bowel disease (PMID: 37253738).

The research also found that transplanting gut bacteria from mice exposed to Red 40 into unexposed mice was enough to increase their susceptibility to colitis. The dye had shifted the microbiome so much that the changes were transferable.

A separate 2024 study on Yellow 6 in rats found similar patterns: microbiome imbalances, reduced beneficial bacteria, increased pathogenic microbes, disruption of the gut lining and activated inflammatory pathways (PMID: 38490351).

These studies used doses calculated based on the FDA’s acceptable daily intake, not extreme amounts.

The Protein Binding Issue

Artificial dyes bind to proteins. This includes proteins in the food you eat, proteins in your blood and proteins in your tissues.

This is why your tongue turns blue or red when you eat brightly colored candy. The dye molecules are literally binding to the tissues of your mouth.

Research has shown that food dyes like tartrazine (Yellow 5), sunset yellow (Yellow 6) and amaranth bind to human serum albumin (the most abundant protein in your blood plasma). The binding is strong enough to potentially influence how albumin functions.

When dyes bind to food proteins, they can affect how your digestive enzymes interact with those proteins. This may disrupt normal digestion and increase the likelihood of downstream issues like immune reactions.

When dyes bind to body proteins and tissues, there’s research suggesting the immune system may not recognize those altered proteins as “self.” A 2015 study on food coloring and immune reactivity found that artificial colorants binding to body proteins may have significant immune consequences (PMID: 25599186).

What’s Actually Changing Now

In April 2025, HHS and FDA announced a plan to phase out all petroleum-based synthetic dyes from the American food supply by the end of 2026. This is a voluntary transition plan and not legally binding, but it’s one of the most significant shifts in food additive policy in decades.

Here’s what’s happening:

Already Banned:

Red No. 3: Officially banned January 15, 2025. Food manufacturers have until January 2027 to reformulate, drug manufacturers until January 2028.

In Process:

Citrus Red No. 2 and Orange B: FDA is initiating removal proceedings in the coming months.

Voluntary Phase-Out (by End of 2026):

• Blue No. 1

• Blue No. 2

• Green No. 3

• Red No. 40

• Yellow No. 5

• Yellow No. 6

The FDA is also fast-tracking approval of natural alternatives. Galdieria extract blue, butterfly pea flower extract, calcium phosphate and gardenia blue have already been approved or are in the pipeline.

The Consumer Brands Association committed to removing synthetic dyes from foods served in schools by the 2026-2027 school year.

California passed the California School Food Safety Act that bans certain synthetic dyes from meals served in public schools starting in 2027. Arizona passed a similar law. West Virginia announced plans to eliminate synthetic dyes from school meals by 2026. Multiple other states have legislation pending.

Avoiding Artificial Colors

The simplest approach is to minimize processed foods altogether. The less you eat from foods that have ingredient labels and instead just consume the ingredients themselves, the less you have to worry about what’s in them.

But synthetic dyes show up in places you wouldn’t expect. Smoked salmon. Pickles. Salad dressings. Cheese. Many products marketed as “natural” use them. Reading ingredient labels on everything you buy is a habit worth building. You’ll start noticing a lot more than just artificial colors.

Check your medications too. Many pills, syrups and children’s medications contain synthetic dyes. So do some supplements.

When you do buy packaged foods, here’s what to look for on labels:

• FD&C Blue No. 1 (Blue 1, Brilliant Blue)

• FD&C Blue No. 2 (Blue 2, Indigotine)

• FD&C Green No. 3 (Green 3, Fast Green)

• FD&C Red No. 40 (Red 40, Allura Red)

• FD&C Yellow No. 5 (Yellow 5, Tartrazine)

• FD&C Yellow No. 6 (Yellow 6, Sunset Yellow)

If you want color in your food, there are real alternatives that come from actual plants:

• Beet juice or betacyanin (red)

• Turmeric (yellow)

• Spirulina or chlorophyll (green)

• Butterfly pea flower or red cabbage (blue/purple)

• Paprika or annatto (orange)

• Cocoa or coffee (brown)

The Bigger Picture

When it comes to stuff like this, people will always say “yeah but at small amounts it’s perfectly fine.” And that’s fine. Consume whatever you’re comfortable with.

But I think it’s worth asking yourself if something has very clear negative health impacts at any amount, are you fine with consuming it? Especially something that is entirely unnecessary, has zero added value (unless you truly care how colorful your food is) and is made from petroleum?

The phase-out of synthetic food dyes is happening because the evidence finally became impossible to ignore. Not because it was new. It’s been accumulating for 50 years. It’s happening because enough states passed their own laws that the FDA had to act.

This is a pattern worth recognizing. The FDA waited 35 years after learning Red 3 caused cancer to ban it from food. They’ve known about the behavioral effects for 50 years and are only now addressing the remaining dyes.

The lesson here is to be proactive. Don’t wait for regulatory agencies to protect you. Just because something isn’t banned doesn’t mean it’s safe. And don’t wait for the perfect randomized controlled trial before you make a decision. When it comes to processed foods, your intuition that eating petroleum-derived chemicals probably isn’t a great idea? Trust it.

The companies selling you these products already know how to make them without synthetic dyes. They do it for European consumers. They’re about to do it here.
